/IwE/I/o Q n/f Moss/5w? BI AMM ATTORNEY FRANK MOSSBERG, F ATTLEBORO, MASSACHUSETTS, ASSIGNOR '1.0 MOSSBERG PRESSED STEEL CORPORATION, OF ATTL-EBORO, MASSACHUSETTS, A CORPO- BATION 0F MASSACHU$ETTS nascere.

To all 'whomt may concern:

Be it known that I, FRANK MossnRe, a citizen of the United States, and resident of the city of Attleboro, in the county of Bristol and State of Massachusetts, have invented certairf new. and useful Improvements in Bobbins, of 'which the following is a specification.

This invention relates to bobbins more particularly adapted for use on braiding machines; and has for its object to provide such a bobbin having a non-metallic tubular body portion and a metal ratchet-toothed head with specially constructed means for connecting the body to the head :by which construction a bobbin will 'be particularly li ht and strong rendering it particularly a aptable for use in a braiding machine. l

With these and other objects in view, the

invention consists of certain novel features of construction, as will be more fully described and particularly pointed out in the l appended claims.

In the accompanyingdrawings:

vFigure 1- is a sectional side elevation of my improved bobbin.

Fig. 2- is a, bottom-end view of the same.

Fig. 3 is a side elevation showing a modified form of my improved bobbin.

Fig. 4.- is a bottom end of the bobbin shown in Fig. 3.

Referring to the drawings, 10 designates the tubular body portion of my improved bobbin, which is preferably made of wood but which may be made of any suitable nonmetallic material. rIhis body portion is provided wtha hole 11 through it for the purpose of receiving the spindle of the carrier on which it is designed to be mounted.

At the lower end of this body portion is a head-member 12 which is constructed of metal in disk form having its edge or periphery turned downwardly as at' 13 and notchedto form ratchet teeth 14 which may be engaged inY any of the usual ways for thel purpose of controlling the let-off motion of the yarn 15 on the bobbin.

In o-rder to securely attach this wooden body-portion to the head, I have -provided a ferrule 16 formed of thin metal, and having a laterally-extending flange 17. The lower end of this body portion' is fitted l,tightly into the body of the ferrule and the side wall of the errule is forced or bent inward at BOBBIN. l X

' intervals as at 18 to serve as a key to secure theJ two together, The flanged portion 17 of this ferrule is set slightly inwardly as at 19 and 1s secured to the head member by rivets 20, spot-welding or by any other suitable means.

By this construction where the flange is attached to the under side of the head 12 it w1ll be seen that the body portion of the ferrule may be comparatively long thus proyiding the maximum length of the end bearing for supporting the wooden body in uprlght position. A

In other cases I form the base member of sheet stock and "bend the edge 23 downwardly, and form ratchet teeth 24 thereon, .and I also form a ferrule 25 with its flange secured to the upper face of the hea-d, and having its body portion 26 arranged to eX- tend downwardly through this head and in' this ferrule the lower end of the wooden `body 27 is attached.

. Another advantage in forming the body portion of the bo'bbinof wood is that in practice it is found that one made of wood will run more satisfactorily on the metal spindle without lubrication than will one made of metal.

By forming a bobbin of my improved construction With the body-portion of wood or liber and the base of metal, it will be seen that the upper part of the body-portion is extremely light in weight which is of great but I desire it to be understood that I reserve the privilege of resorting to all the mechanical changes to which the device 1s susceptible, the invention being defined and limited only by the terms of the appended claims.

I claim:

1. 'A braider lbobbin having a non-metallic tubular body portion, a metal head at one end of said body having ratchet teeth said vimportance in the use of braiding machines,

head being provided with a central opening into which one end of Said body is xed.

2. A braider bobbin having a non-metallic tubular lbody portion, a metal head having teeth formed on its edge, and a bendable metal 'e-rrule into which one end of said body is Xed and the flange of said ferrule is connected to :said head.

3. A braider -bobbin having a non-metal-pv lie tubular body portion, a metal head meinber having its periphery turned downwardly and ratchet teeth formed therein, a comparatively thin metal ferrule in which one end of said body is secured, and said ferrule having;v a :flange secured to said head.

In testimony whereof I aiix my signature.

FRANK MO SSBERG.
